BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Jul s, rein.

To all whOm it may concern:

W. H. CLAY, a citizen of the United States, residing at State ofPennsyl- Improvements in Bottle-Closln'es, of which the following is aspecification.

My invention relates to metallic caps for jars, etc., and particularlyto means for locking and unlocking the closure.

The invention is illustrated in 01 f as applied to a mi k bottle in theaccom panying drawing, wherein Figure 1 is-a central vertical sectionofa jar with a cap in place thereon. Figs. 2 and 3 are side elevationsat right angles to each other of a cap provided with an opening device,Fig. 4 being a plan view of the same. Fig. 5, shows an alternative formin which the locking flange is locked against opening. Fig. 6illustrates the mode of cutiling the blank for this latter device, andFig.

is a side elevation of the locking lugs in place.

In several patents heretofore granted to me I have shown a bottle capwhich engages the glass by the edges of a slotted metal flange, so asnot to depend upon friction for the hold. on the bottle, such caps alsohaving the feature of maintaining a pressure by the strain of the metalitself rather than by the elasticity of the packing employed. As shownherein, I may provide a cap 8 with a paper packing 9 resting on themouth of the bottle 10, the sides of the cap 11 being in loosecircumferential contact with the bottle flange and the slotted andindented parts of the flange 12 directly engaging the glass by the edgeof the metal. Properly proportioned the inwardly bowed portions 12 mustbe sprung outward in order to go over the bottle flange as pressure isapplied and when such pressure is removed the arches 12 have a directhold on the glass and are placed under a downward stress. As long as theparts are in position as shown in Fig. 1, it is evident that anypressure under the cap. pushing the arches 12 upward, also tends toforce them inward andthcrefore locks the cap tighter. Meanwhile the sealis kept by the resiliency of the metal in the arches 12. If thegenerally conical shaped skirt formed by the series of inward arches 12and the intervening connecting arches 13 be in, anywise expandedcircumferentially,

the hold of the arches 12 may be loosened,

and only by such separating of this conical skirt can the cap beremoved. My present improvement contemplates any means for expanding theconical skirt. For instance, I may provide the two lugs 1t and 15 turnedup out of the metal of the skirt as shown in v Figs. 2, 3 and 4, so thatby pushing one in one direction and one in the other, the skirt can bespread and the cap removed. This is easily done with the thumb andfinger or any convenient tool for applying twisting movement tothe lugs.In this form of the cap, the application to the bottle is made by simpledownward pressure, snapping the cap over the bottle-flange and to betterits hold on the bottle, I may provide the rib 16 shown in Fig. 2, orother stiifening means.

Generally, there should be only enough metal on the outward arches 1.3,to safely hold the flanged skirt and stand the pressure necessary wherethe cap is applied by aring engagin the arches 13 as in my previousPatent o. 860,964, July 23, 1907. Thepresent cap however, is easilyapplied by. 1

and pressure and can be used over again indefinitely, the metal notbeing permanently distorted.

In some instances itis desirable to ,absolutely lock the cap on thebottle, and in such case the opening lugs may be made as shown in Figs.5 to 7. The punched out portions 17, 18, are turned up at right anglesso that the lug 19 engages the side of the lug 18, thus preventing amere pressure on the sides of parts 17,-1.8, from releasing the cap. Therelease is accomplished by a slight vertical displacement of the lugs18and17 either with the fingers or by inserting a sharp tool in thesmall slot (20). As shown in Fig. 7 a. bit of sealing wax may be appliedat X so that the bottle cannot be. opened without breaking the seal. Itwill be seen that this provides ready means for sealing certified milk,etc. The same end can be accomplished with the form of lug shown in Fig.2 as by sealing the lugs 14, 15, together. The cap may be attached tothe bottle by a wire through any opening therein and around the bottleas through Q the lug 15.

Theadvantage of a bottle or jar cap which may be repeatedly applied bymerely springordinary blows and not disturbed by inside pressure in thebottle; which keeps its seal by the resiliency of the metal itselfrather than by the packing which may be removed by hand, and which maybe at the same time sealed without interfering with the hancl openingfeature, all how from the peculiar construction shown and the manyadvantages oi the device will be apparent to those familiar with theart.

Having thus described my inyention and illustrated its use, What I claimis the following 1. A bottle sealing cup having a generally conicalshaped flange with horizontally slotted portions engaging by their edgesthe flange of the bottle, and means for spread ing the said conicalshaped flange to re lease the hold on the bottle.

'2. The combination with flanged-I lrottle mouth of'a metallic sealingcap comprising; a cover, a circumferential flange of general conicalform slotted at intervals and the slotted portions bowed inwardly toengage the bottle flange on the eclge of the metal,

of a pair of lugs arranged on the cen' skirt and. adapted tocircumferential1y spreac' the skirt, substantially as described.

3. A bottle sealing cap comprising a cover and a dependent flange havingeircmnfen .26

loosening the grip of such arches comprising projections on the skirt ofthe cap adapt ed to be moved by hand, substantially as described.

In testimony whereof I have hereuntosigned my name in the presence ofthe two subscribed Witnesses.
